The start of August means more heat, humidity and unfortunately, no rain in sight. Except for stray sea breeze showers, it looks the dry weather will continue into next week as the heat ramps up. The sprawling ridge of high pressure aloft will strengthen slightly and settle over Texas next week keeping us in above average temperatures. The dry weather and light to moderate winds will give us good weather for outdoor activities through the weekend but you'll want to be careful not to overheat as heat indices will climb to 102-107 each day. Remember to stay hydrated, take frequent breaks and avoid strenuous activity.
During the month of August we normally see the biggest increase in tropical activity with the peak usually around September 10th. As of now there are no tropical systems forecast to affect south Texas in the next week. There is a tropical disturbance in the Atlantic which has s 70% chance of development in the next 5 days. It is located about 1100 miles west-southwest of the Cabo Verde Islands. Slow development of this system is expected during the next few days while it moves west-northwestward, and a tropical depression is likely to form several hundred miles east of the Lesser Antilles. Environmental conditions are now forecast to become unfavorable for additional development by early next week as the system approaches the Lesser Antilles.
